COMPENSATION-TYPE PENDULUM ACCELEROMETER Russian patent published in 2015 - IPC G01P15/13 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measuring devices of linear accelerations. Essence of the invention is as follows: accelerometer includes housing (1), in which there is pendulum plate-like sensitive element (PSE) (2) arranged, an elastic suspension by means of which PSE is connected to housing (1); magnetoelectric torque sensor (3), photoelectric sensor (6) of travel angle, and compensation amplifier (10). The elastic suspension consists of two coaxially located metal struts (7) with a rectangular cross-section, which are fixed in PSE (2) and in housing (1), and strut (7) fixation device (8). Metal struts (7) are current leads to outputs of coils (5) magnetoelectric torque sensor (3). With that, both struts (7) are installed so that their larger side of the section of parallel to the longitudinal axis of coils of megnetoelectric torque sensor (3).

EFFECT: increasing dynamic range of measurements; providing a low value and high stability of zero shift of the instrument, and providing reliability under conditions of mechanical actions.
